## Discrepancy

IT OCCURRED WHEN PERFORMEING AN OUTGOING ENGINE RUN.  WHEN THE THROTTLE WS PULLED BACK TO IDLE, ON THE S TOP OF THE SERVO, WHEN WE PULLED A LITTLE HARDER, IT CAUSED THE ENGINE TO STALL AND SHUTDOWN INSTEAD OF JUST DECREASING A FEW MORE RPM.  RECOMMEND SB TO CHECK ALL MFG AC FOR THIS CONDITION.  (K)
